Becklard’s Physiology from the 1840s is a pocket-sized textbook authored by Dr Eugene Becklard M.D. The compact size of 3”x4 1/2” makes it convenient for on-the-go learning, and its translation from the 3rd Paris edition ensures accessibility to a wider audience. This textbook provides valuable insights into physiology during that era, making it a valuable resource for students and educators interested in historical medical texts.
